The Rally 1200's hard surface tool uses two streams of 1200 PSI water to turn the spray bat at up to 1400 RPM. This high pressure spray helps remove soil from the tile and grout. A vacuum shroud surrounding the tool pulls the dirty water into the recovery tank. Continuous water supply keeps your staff productive on large jobs. Use standard garden hoses to supply water to and drain water from the Rally 1200. Not just for hard floors. Reduce the pressure and it can be used as a cold water carpet extractor. Easy maintenance. By removing a single bot, the tank can be tilted back, revealing the inner workings of the machine.
